[Seaside] Weird back button problem

[Johan Brichau]

Larry,

I'm really answering off the top of my head now, but nested html forms are indeed not allowed. It's likely that this is causing the trouble.

You might consider replacing the cancel button with a cancel link (i.e. an anchor with 'cancel'). That probably will give you the behavior you are looking for.
I'm never using a cancel button because we do it with links throughout the application.
